HEATING APPARATUS FOR ATOMOBILES.

To all lwhom it may concern Be it known that we, (1) REGINALD A. BAILEY and (2) MAX l?. W. lPLrsKE, citizens of the United States of America, residing at (l) New Castle and (2) Cleveland, in the counties of (l) Lawrence and (2) Cuyahoga and States of (l) Pennsylvania and (2) hio, have invented certain new and useful Improvements in Heating Apparatus for Automobiles, of which the following is a specification, reference being had therein to the `accompanying drawing.

lhis invention relates to heating apparatus for automobiles and -other engine driv-en vehicles, and the primary object of the invention is to utilize the exhaust of an engine for heat-ing the passenger compartment of an automobile, to add to the comfort of the passengers, particularly during,`

winter travel.

Another object of the invention is to? furnish a radiator with a heating coil that can be easily cleaned and maintained in an operable condition.

A fur-ther object of the invention is to of the novel construction, combination and arrangement ofV parts to be hereinafter specifically described and then claimed. y

Reference will now be had to the drawings forming part of this specification,

wherein there is illustrated a preferred ernbodiment of the invention, but it is to be understood that the structural elements thereof are susceptible to such changes as fall within the scope of the appended claim.

connection between the slide 13 and the Iof the radiator and has one end thereof pro- `said coil having` the inlet bipe 2O and the Patented July 22, l 913.

serial no. 599,223.

this invention embodies a radiator and in the radiator is located a one-piece coil which is connected to the exhaust pipe of an internal combustion engine, the radiator being located in the floor of an automobile compartment and provided with means whereby it can be easily closed and opened to admit hot exhaust gases to the coil.

The radiator comprises end walls l and 2, said walls having the lower and vertical edges thereof flanged inwardly, as atl 3 and the upper edges thereof flanged outwardly, as at 1l. Side walls 5 and G are held in place by the flanges 3, said side walls having the upper edges thereof flanged (mtwardly, as at 7 and the lower edges thereof' flanged inwardly, as at 8.

l Supported by the flanges-fl and 7 of the walls l, 2, 5 and G is a grate or perforated cover plate 9 having the ends thereof provided with apertures l0 adapted to aline with similar openings in the flanges Il and 7, whereby the radiator can be secured to the floor of an automobile in a suitable opening provided therefor. The grate is secured to the upper edges of the walls l, 2, 5 and (l by set screws l1 entering brackets l2 suitably secured to the inner sides of the walls The flanges 8 of the walls 5 and (l support a slide 13, said slide having the longitudinal edges thereof bent to provide longitudinal guides le adapted to ride upon the flanges 8, said guides forming a dust and dirt proof lower edges of the walls 5 and 6. The slide '13 is of a length corresponding to the box vided with a depending handle or grip l5, whereby the slide can be easily removed from the box of the radiator when it is desired to cleanse the interior thereof.

Secured to the inner sides of the walls 5 and by screws or other fastening means 16 and lf? are two stirrups 18, these stirrups supporting a one-[nece horizontal coil 1S),

outlet pipe 2l thereof held upon the stirrups 18 b v clamps 22 secured to the upper ends of the stirrups 18 by the screws or other fastening means 1G. The outlet. pipe end of the coil is connected to the inlet pipe end thereof by a pipe 41, which can be formed integral with the coil or made separate, the object of this pipe being to relieve the pressure in the supply end of said coil. The coil 19 is preferably made of aluminum and has the end thereof adjacent to the end wall 2 provided with nipples 23 normally closed by detachable screw plugs 24e. In order that the nipples can beeasily removed and the coil cleansed, the end wall 2 is provided with openings 25 normally closed by shutters Q6 pivotally connected to the outer side of the wall Q, as at 27. By reason of the by-pass 41a, the pressure of the exhaust on the initial or first bend is relieved to such an extent as to reduce the pressure on the supply end of the coil to a point where such pressure will not affect such end when the coil is made of. comparatively thin metal. Hence the coil willprovide a maximum eiliciency of heat with a minimum weight.

A suitable device for cleaning the coil comprises a disk or head QS connected to a ilexible rod 29 having the opposite end thereof provided with a suit-able handle 30. The cleaning head :28 can be easily shifted in the convolutions, of the coil to remove carbon or other matter that might adhere to the inner walls of the coil.

The inlet pipe 20 of the coil terminates in the radiator and is coupled to a conventicnal form of butterfly valve 3l, said valve having the shutter or leaf 32 thereof mounted upon a stem 33 extending through a stufling box 34e, carried by the valve 3l. rlhe outer end of the stem 83 is provided with a crank Bfand loosely connected to the cuter'end of the crank is a. link 3G, said link being connected to a boss 37, carried by a pivoted tread lever 3S connected .by a bolt 39 to a bracket 40 suitably secured to the inner side of the wall l. The lower end of the bracket isprovided with anextension etl in parallelism with the lower edges of the walls 5 and G, said bracket being located centrally of the radiator box whereby theextension l-l thereof will serve functionally as a guide for the inner end of thev slide 13. The pivoted tread lever 38 prot-rudes through an opening 42 provided therefor in the gratev 9 and the. upper edges of said tread lever are serrated or roughened, whereby it can be easily shifted with the foot.

The valve 31 is connected by a branch pipe 43, a flexible connection 44 and an elbow t5 to' a coupling 4G located upon the main exhaust pipe 47 of an internal combustion engine 4S. The exhaust pipe t7 is provided with a niufller 49, and the outlet pipe 21 is connected to an exhaust 50 extending rearwardly and havingl a small mufHer 5l.

As will be seen, the connections between the heating attachment 9 and the exhaust pipe are valve-controlled, While the exit for the exhaust gases from the heating coil is permanently open exceptincr for the back pressure provided by the independent muftler 5l. Consequently, in use, the amount of gases which are passed through the coil may be controlledx without affecting the operation of the device by backV pressure, it being readily understood that since the muffler 5l is intended to provide for action when the maximum amount of exhaust is introduced into the coil, a reduction in the gases introduced will decrease the amount of pressure provided by said mutiier, and the pressure produced by the muffler will be proportional to the amount of gases passing therethrough, insuring a circulation of the heated gases through the coil regardless of the amount which is introduced.

It is thought that the operation and utility of the heating apparatus, particularly in connection with an automobile for utilizing the exhaust of the engine thereof will be ap parent without further description, and it is to be understood that the radiator can be made of various sizes and materials and the walls thereof lined with asbestos or any suitable non-fusible mate-rial.

lt is obvious that the heating apparatus therethrough7 the outlet end of the coil being located at the same end of the casing with the inlet end and, being permanent-ly open, a pipe leading from said outlet end, and a mufller carried by said pipe, said muftler being operable solely with said coil, the legs of said coil adjacent to the inlet and outlet ends of the coilbeing connected by a permanently-open by-pass to relieve the supply end of the coil from excessive pressure. sure.

In testimony whereof we atHx our signa` tures in the presence of tw'o witnesses. A REGINALD A. BAILEY.
